SC-SEN (GRAHAM): Sen. Lindsey Graham (R-S.C.) persevered in his primary election, winning the race by 40 points. However, Smart Politics reports that Graham took the lowest share of the primary vote of any sitting U.S. senator in a Republican primary — in part due to the fact that he was facing six primary challengers. Compared to his South Carolina predecessors, Graham received the lowest support of any elected senator in either party since 1950.

OK-SEN (OPEN): A group backing T.W. Shannon in the Oklahoma Senate Republican primary, Oklahomans for a Conservative Future, released a new survey showing him up over Rep.

That’s a drop in support from the group’s last survey, conducted in April, which showed Shannon leading Lankford 42-32.

Bill Owens’s (D) seat, hitting him on labor and tax disputes he’s faced previously and calling him a “perennial loser.” He’s facing Elise Stefanik, the establishment pick, for the chance to take on Democrat Aaron Woolf in the general.

CLINTON:A Gallup poll released Wednesday reveals that Hillary Clinton’s approval rating has dipped slightly in recent months, dropping from 59 percent in February to 54 percent. Though she is still favored by a majority, this new rating is her lowest since August 2008.

On the second day of her book tour, she again drew ridicule from Republicans, this time for misidentifying Abraham Lincoln as a senator from Illinois — her home state — when he was in fact a member of the House before he became president.

Clinton also said her comments that she and foerm President Clinton were “dead broke” when they left office were “not the most artful.”
